We know that most plants use carbon dioxide to make their own food. So what might plants look like in 100 years if carbon dioxide levels continue to increase - will they become enormous and overtake our backyards? View the possible effects of changes in atmospheric carbon dioxide on plants and, in turn, humans and other animals.

This is a multilayered resource about the theories and evidence of the origins of the first modern humans in south-east Asia. It has four sections: Theories; The sout-heast Asian fossil record; The appearance of sout-heast Asian features; and The first modern Indonesians. The Related sections, Related items and Related ...

This is an interactive resource about how greenhouse gases affect the climate. Students use a simulation to explore the atmosphere during the ice age and today. They change variables such as adding clouds, changing greenhouse gas concentrations and see how the temperature changes. They can then compare this to the effect ...

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. This TedEd animation (4:58 ...

Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?

Explores the global carbon and water cycles as well as the role that plants play in these cycles with particular emphasis on the stomata in the leaves. Also looks at human impact on these cycles and the climate. Includes videos, simulations showing changes over time, graphs, maps and a detailed glossary section. Free when ...

What does 'horsepower' really mean? And how do engines work? Join Luke and Abhi from MIT to find out! As Abhi explains, engines produce power by forcing a mixture of fuel and air into a tight space and then burning it. Piston engines and turbine engines do this in similar, yet different ways. After watching this video, ...

Is carbon capture and storage (CCS) the solution to climate change? CCS technology captures carbon dioxide from the flue gases of coal burning power plants and takes it to long-term storage. The coal industry has high hopes that pumping the liquefied gas into underground reservoirs, or geo-sequestration, will provide safe ...
